This merge window brings a good size of cleanups on various platforms. Among the bigger ones: * Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have lacked active support for quite a while, and after asking around nobody showed interest in keeping them around. If needed, they could be resurrected in the future but it's more likely that we would prefer reintroduction of them as DT and multiplatform-enabled platforms instead. * OMAP4 controller code register define diet. They defined a lot of registers that were never actually used, etc. * Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate) to drivers/soc so it can be shared with 64-bit code. This also converts them over to traditional driver models where possible. * Removal of legacy gpio-samsung driver, since the last users have been removed (moved to pinctrl) Plus a bunch of smaller changes for various platforms that sort of dissapear in the diffstat for the above. clps711x cleanups, shmobile header file refactoring/moves for multiplatform friendliness, some misc cleanups, etc. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAABAgAGBQJT5DYPAAoJEIwa5zzehBx37egQAIiatNiLLqZnfo3rwGADRz/a POfPovktj68aPcobyzoyhFtToMqGvi9PpysyFTIQD2HJFG+5BtiIAuqtg0875zDe EpBWgsfugrm0YktJWAtUerj60oAmNPbKfaEm1cOOWuM2lb2mV+QkRrwSTAgsqkT7 927BzMXKKBRPOVLL0RYhoF8EXa0Eg8kCqAHP8fJrzVYkRp+UrZJDnGiUP1XmWJN+ VXQMu5SEjcPMtqT7+tfX455RfREHJfBcJ1ZN/dPF8HMWDwClQG0lyc6hifh1MxwO 8DjIZNkfZeKqgDqVyC17re7pc7p8md5HL8WXbrKpK0A9vQ5bRexbPHxcwJ1T/C2Y 465H+st5XXbuzV1gbMwjK1/ycsH0tCyffckk8Yl/2e1Fs7GgPNbAELtTdl+5vV1Y xmDXkyo/9WlRM3LQ23IGKwW7VzN86EfWVuShssfro0fO7xDdb4OOYLdQI+4bCG+h ytQYun1vU32OEyNik5RVNQuZaMrv2c93a3bID4owwuPHPmYOPVUQaqnRX/0E51eA aHZYbk2GlUOV3Kq5aSS4iyLg1Yj+I9/NeH9U+A4nc+PQ5FlgGToaVSCuYuw4DqbP AAG+sqQHbkBMvDPobQz/yd1qZbAb4eLhGy11XK1t5S65rApWI55GwNXnvbyxqt8x wpmxJTASGxcfuZZgKXm7 =gbcE -----END PGP SIGNATURE----- Merge tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Olof Johansson: "This merge window brings a good size of cleanups on various platforms.
